Schizophrenia (subtypes)
Schizophrenia is classified differently in the ICD-10 compared to the DSM-5. Note that the DSM-5 has done away with the subtypes of schizophrenia as they were considered to be valid.
Paranoid schizophrenia is characterised by the preoccupation of delusions or hallucinations (typically persecutory or grandiose ones).
Disorganised schizophrenia (aka hebephrenic) is characterised by a regression to a primitive, unorganized form of behaviour. Incongruous behaviour such as grinning is common.
Catatonic schizophrenia is characterised by marked disturbances in motor function such as stupor, posturing, and rigidity.
Residual schizophrenia refers to patients who lack active psychotic symptoms but still have milder symptoms such as emotional blunting, and mild loosening of association.
Simple schizophrenia is characterised by predominately negative symptoms of schizophrenia in the absence of overtly psychotic experiences.
Bouffee delirante refers to a brief shorted lived psychosis that lasts less than 3 months.
